を特徴とする給紙装置。 It has a paper feed roller for feeding paper, a bottom plate for stacking paper, and a bottom plate lift lever for raising and lowering the bottom plate, and when the bottom plate lift lever is actuated, the bottom plate is raised. In a paper feeding device that feeds the paper by bringing the paper to a paper feeding position corresponding to the paper feeding roller and rotating the paper feeding roller in this state, an operation configured substantially integrally with the bottom plate lifting lever. a lever, a driving means for reciprocating the actuating lever prior to rotation of the paper feed roller in order to raise and lower the bottom plate via the bottom plate elevating lever, and allowing a predetermined amount of free movement for the actuating lever. a driven member that is fitted in the actuating lever and operates in accordance with the reciprocating movement of the actuating lever; and an engagement that engages with a ratchet formed on the driven member to prevent the driven member from operating only in the backward movement direction. a stop member, a rise regulating means for regulating the rise of the paper in a state in which the paper is in pressure contact with the paper feed roller due to the forward movement of the operating lever, and a rise regulating means for regulating the rise of the paper when the paper is in pressure contact with the paper feed roller; 1. A paper feeding device comprising: an engagement release means for releasing the engagement.
